What grains contain male gametes?
Male gametes are found in the pollen grains of plants. These pollen grains are produced in the male reproductive organs of plants, such as stamens in flowering plants. They are the equivalent of sperm cells in animals and are necessary for fertilizing the female gametes, which are typically located in the ovules.
Contain the sperm in seed plants?
Sperm in seed plants are contained within pollen grains, which are produced by the male reproductive organs of the plant. The pollen grains are transferred to the female reproductive structures either by wind, insects, or other means, where they release the sperm to fertilize the eggs. This fertilization process leads to the formation of seeds.
Why is there a need for pollen tubes?
Pollen tubes are necessary for the transportation of sperm cells to the ovule in plants for fertilization to occur. They provide a pathway through which the sperm cells can travel to reach the egg cell, enabling the process of sexual reproduction in plants.
Why do pollen grains have germ cells?
Pollen grains contain germ cells (sperm cells) that are essential for fertilizing the egg cell in the ovule of a flower, leading to seed production. The germ cells are the male gametes that are responsible for the sexual reproduction of plants.
Can you show me a model on how fertilization in plants work?
During fertilization in plants, pollen grains containing male gametes land on the stigma of the pistil. A pollen tube then grows down the style and enters the ovary, where the sperm cells are released. Fertilization occurs when one sperm cell fuses with the egg cell, forming a zygote, while the other sperm cell fuses with polar nuclei to form endosperm.
What are grains that produce sperm cells called?
Microspore mother cell after undergoing meiosis produces pollen grains, and the pollen grains during germination produce sperms by undergoing pollen mitosis.
What contains the plant sperm?
The plant sperm is contained within the pollen grains produced by the anther of a flower. Pollen grains are the male gametophytes of plants and contain the male reproductive cells that will fertilize the female ovule.
What the function of the pollen grains?
Matured pollen grains contained sperm cells. When Pollen grains are sticky, you have pollen. Pollen grains are contained in the pollen sac, with the purpose of helping plants reproduce.

What are male gametophytes called?
Male gametophytes of seed-producing plants are called pollen grains. These are the structures that produce the male gametes, known as sperm cells, which are required for fertilization to occur. Pollen grains are dispersed through the air or by insects to reach the female reproductive structures of plants.
In plants what are the names of male sex cell and female sex cell?
for humans it is sperm and for plants not sure Answer All animals and plants produce sperm cells and egg cells/ova. Some textbooks refer to the male sex cell as simply the male sex cell/gamete. It seems it should rather always be called a sperm cell as that is what it is. Angiosperms produce microspores/pollen grains which grow male gametophytes within themselves, which produce sperm cells.
What most closely represents the male gametophyte of seed-bearing plants?
The male gametophyte of seed-bearing plants is represented by pollen grains. These pollen grains are produced in the anthers of flowers and contain the male gametes (sperm cells). When pollen is transferred to a compatible stigma, it germinates, forming a pollen tube that facilitates fertilization by delivering the sperm to the ovule. This process is crucial for the reproduction of seed plants.
The sperm cells of a flowering plant are contained where?
In plants they are called gametes not sperm cells. The male gametes are found in pollen grains and the female gametes in the ovules (eggs). In angiosperms they are found in the parts of the flowers. Pollen is found in the anthers (male part of the flower) which are in the centre (attached to the fillament-like stamens) of the flower, the anthers and stamens surround the stigma and style (female parts of the flower). In gymnosperms they are found in the male and female cones attached to the plant.
What does fertilization not require in most seed plants?
Fertilization in most seed plants does not require swimming sperm, as they are transported within pollen grains and delivered directly to the plant ovule for fertilization to occur. This eliminates the need for water as a medium for fertilization, unlike in non-seed plants or aquatic plants where swimming sperm are necessary to reach the egg.
Where sperm form in seed plants?
Sperm cells in seed plants are typically formed within the pollen grains, which are produced in the male reproductive structures of the plant (anther). When the pollen grain reaches the female reproductive structure (ovule) of the plant, the sperm cells are released and fertilization occurs.
